Yesterday, I looked through a straight Pentax 80ED scope mounted with the XW14 eyepiece. The XW14 results in a very impressive 36X magnification coupled with 20mm of useable eye relief and a very wide field of view. I was, to say the least, quite impressed with the image. I'm not sure if anything is lost with the angled version, but I would be quite happy with what I saw yesterday. I'd probably skip the zoom altogether and go with the XW14 (36X) and the XW20 (26X).
